Videos of espresso extractions - Page 4

[HB]

Dan, I thought you had the green light for a dedicated espresso bar in the house or basement? Cabinet heights be damned, no?

My lovely bride did indeed give the green light, but I hesitate to encroach on my kids' play area. They've completely taken over every square inch of the basement with toys, videos, games, puzzles... the usual kid chaos. An espresso bar doesn't mesh well with that ambiance. At least my espresso gear in the kitchen looks like it belongs. We're discussing a kitchen renovation, which has opened up other possibilities (however lobbying for a dedicate espresso bar in the kitchen hasn't gained any traction).

Even though they use conical burrs, don't the grinds still have to make a right angle turn to exit into the doser? That would still produce clumping and I would imagine there is little difference between the Major and Kony in regard to clumping because of that

I've used the Robur at Counter Culture during our regular Friday espresso labs. It doesn't produce the perfectly even distribution of the Versalab M3, but it's miles better than my Mini. Although they both have the same ejection pathway, the Robur hurls the grinds out with considerably more force and the grinds are less compacted by the experience. The grinds "lay out" more easily, perhaps because of the longer grinding surface of the conical burrs (?). Nick used the Kony in competition and said the grind quality is as good as the Robur, but it's a slower grinder (Greg made the same observation). I can live with a few extra seconds. At some point I'll do a thorough side-by-side comparison, if only to settle the issue in my own mind...

I would expect it to perform better than a mini, but how does it compare to a Major. With the larger burrs it blows the grinds out better.

Not being fortunate enough to have a local cafe that lets me play with their equipment (heck, I don't even have a local cafe), I have never put hands on a Kony or Robur. The Kony sounds promising.

You guys with your 18g naked extractions....like the Free Skate at the Winter Olympics. But let's see how well you do in the unforgiving "compulsories". Let's see a naked extraction from a single basket

The gauntlet has been dropped, I will accept that challenge.

[cannonfodder]

I won't say it was perfect; there is a slow spot, but it was not too bad.

Sorry, no videos - but I did dig up some pix.



I don't often pull singles, especially on my Vetrano (shown). Singles were noticeably easier on my Rancilio L7. There's less clearance on the E61 grouphead, and it's hard to avoid overdosing the Vetrano single basket.

Peggy Fleming: The final impression in the cup might make up for imperfections in the performance, as that's the last thing the judges see.

Dick Button: The performance was balky and tentative and lacked flow. The single basket separates the geese from the ducks.

P.S. Peggy's a sweetheart, but Dick can be a real prick.

[cannonfodder]

Would not disagree at all.

Like I said it was not perfect. The extraction was slow and I had a slow spot. Honestly I normally do better with a single although I don't use them often. I will have to take the tripod home and capture a few more over the weekend. It takes a handful of shots to get the grind and dose set.

My lighting sucked as well. What looks like a dead spot in the back right is actually a reflection off the crema from the light I was using, but no excuses.

But I would have been happy to have been served it Your grind was simply off a tad, as you said. Just a smidgen coarser and your puck would have had better porosity. My single baskets demand a coarser grind than the double, and one of the two single baskets, which is taller than the other and has a sharper angle in the conical section, needs a coarser grind than the other single. Tolerances get narrower on the single.

Now, a video-essay on different extractions with different shaped single baskets would be a very nice reference here on H-B

Do these machines use proprietary baskets?

It's not a video of a single (can't remember the last time I pulled a single on my machine) but it's a different view of the process.

The shot pulled about 4 seconds too long - I blame it on watching the shot pull through the little handheld video camera screen, it messes with my head. I guess if Hollywood ever decides to put out a feature length movie they won't come calling for my camera skills.

[edwa]

Just a quick comment on the video. G-r-e-a-t !

What I liked was not only did it show the whole process, (in the words of Jackie Gleason "How sweet it is!"), but for those of us not familar with that particular machine, we got to hear its noise level. We also got to see the short flush for the double boiler vs. an Hx. Very smooth gives a great impression of the machine its self.

Maybe this clip should be added/linked to the Brewtus review? How about clips for the other reviewed machines, you could get some owners to participate?

Pssst, buddy, wanna see some action shots of La Val?

Thanks,
Ed

Hey just glad another HB'er enjoyed it.

I got the oddest request regarding the video, from an undergrad at Boston College (who by the way seemed like a really nice person). She posted up to my blog to ask if she could use the video (she randomly found it on Google Video) as part of a presentation series she had to make to her class. As it turns out it went very well apparently. I was glad to hear it. I hope she didn't critique my poor camera work and the at least 5 seconds too long shot pull.

Do these machines use proprietary baskets?

I assume QuickMill has their own basket, but perhaps it's a rebadged basket from another manufacturer. Here are side-by-side pix of the two single baskets, QuickMill on the left and Rancilio (?) on the right. Major differences in shape and capacity, so not surprising that they pour very differently.



The E61 group on my Vetrano, while generally more forgiving than the Rancilio group, is much easier to overdose. This becomes a serious issue with the QM single basket. I cannot level the basket to the rim and tamp without hitting the shower screen as I lock in, which practically guarantees channeling. I did not have this problem on the L7.

Pulled a couple more last night, the flow rate was better but I had a smidgen of channeling. Still a good shot.

The problem I am having is dose. The single basket I am using was not made for my Faema, it is from my Isomac. The headspace is non existent. The basket is very shallow and even with barely enough coffee to cover the side taper the puck still contacts the shower screen when I lock it in.

I will have to bring the basket and camera to work (my Isomac and Mazzer are in my office) and pull a few singles on the machine the basket was made for. I SHALL prevail!

Was it a comparative religion or anthropology class? Barista as celebrant at the altar?

Good one!

In order to look up at the PF basket to watch the flow develop, I know I have to kneel down - almost altar like.

[dmankin]

Man, you are all inspiring me to find a spare portafilter for my Gaggia Classic so I can go at it with a dremel tool. Anyone have one sitting around????

Keep the videos coming - I'm learning tons from them.

[Reasnor]

Ok, I hate to show this video because there is so much spraying. It really humbles me. I'm posting at the request of others on a different topic. Basically, I've tried many different distribution and leveling techniques...but ever since I received my naked portafilter, I see a lot of spraying (which was apparently happening all the time with a spouted portafilter).

This was last night. I pulled another shot this morning that wasn't near as bad, but had a 38 second timing. Don't worry...you won't have to look hard for the spraying. This video might more closely resemble an all-out attack on planet drip tray. Enjoy...

Oh yeah, this video is from my digital still camera. First time I've recorded and/or uploaded a video. I was holding onto a flashlight in one hand and the camera in the other. You'll be annoyed by the constant auto-focusing going on and the BRIGHT light. Maybe I'll make a better video soon.
